PDAF at the EGU General Assembly 2021

The research group developing PDAF will be present at the EGU General Assembly from April 19 to 30, 2021 online.

Members of the group give following presentations:

Short Course

SC5.14: Practical data assimilation with the Parallel Data Assimilation Framework
Convener: Lars Nerger | Co-conveners: Wolfgang Kurtz, Nabir Mamnun, Qi Tang, Gernot Geppert Friday, 30 April, 10:00 - 11:00, <a target="_blank" href="​https://meetingorganizer.copernicus.org/EGU21/session/38988">Online</a>

In this Short Course we provide an overview of ensemble data assimilation and how to apply it using PDAF.

For the hands-on example we will provide a tutorial version of PDAF that will be downloadable without registration. The download link will be announced during the short course.

Tutorial code: ​Tutorial code package
Slides: ​Full set of Slides
